Nowadays in the era of the almighty internet connection the easiest way to get an airline credit card is online. A lot of sites have an online selection of airline cards of every sort. More than that, each airline has its own site where you can apply for a co-branded card of that airline. This is indeed convenient for those who fly mostly with this particular airline. For example, if you fly Delta exclusively, then it may be an option to go to the Delta website and choose one of their cards.
However, if you are not 100% sure about which airline card to get, it'd better to browse through the list of options on a website that has all of the offers in one place. That will help you compare perks and bonuses of each card as well as fees and APRs - mind that co-branded airline cards often have high fees for their services. Here you can find a large selection of travel and airline cards that you can apply for.
Yet, there are more options that just airline credit cards. Check out general travel cards that will let you earn rewards not only on one particular airline flights, but on different travel and other purchases. Such cards offer a fast and easy redemption process that won't bother you with blackout dates and limited availability. These cards offer high rewards and generally lower fees than co-branded cards. For example, the Discover it® Miles credit card gives you 1.5 miles on every purchase and matches all the miles you've earned at the end of the first year (if you are a new cardmember). This 1.5 miles per dollar offer is basically the same as most airline offer on their cards, but in this case you can get those miles not only on one airline flights, but on all purchases, and that's going to earn you much more miles as a result.
So, look throught the offers and choose one that fits your spending habits. Getting a credit card has never been easier!
